Pistachios come from the Middle East, and more precisely, from the areas of Persia: even in the present, these are grown in Iran, where tasty fruits come from. Distinguished by a woody drupe, pistachios are seeds whose color is light green, surrounded by a light skin whose color varies between dark purple and brown, depending on the level of ripeness of the fruit. The peculiarity of this fruit is to be found in the fact that it reaches maturity only over a two-year period, with the result that a quantity of fruit is not always obtained such that prices can remain stable.
